The invention relates to a handling mechanical hand for downhole auxiliary drilling operation. The handling mechanical hand comprises a stand column body, a plurality of stand column fastening and welding bodies, a plurality of rear baffles, an executing body and hydraulic cylinder clamping rings, wherein the stand column body is used for supporting the whole handling mechanical hand, the plurality of stand column fastening and welding bodies and the plurality of rear baffles are fixed to the stand column body, the executing body is fixed to the top of the stand column body, and the hydrauliccylinder clamping rings are fixed to the rear baffles. The plurality of stand column fastening and welding bodies sleeve the stand column body side by side. Each rear baffle is transversely fixed to the corresponding stand column fastening and welding body and is fixedly connected with the corresponding hydraulic cylinder clamping ring and fixed to a downhole hydraulic support oil cylinder throughthe hydraulic cylinder clamping ring. The executing body can do telescopic movements and is used for realizing hoisting at different stations. The handling mechanical hand is adjusted to reach a proper working height through the stand column body, and a downhole drilling apparatus is hoisted through the cooperation of the stand column body, the hydraulic cylinder clamping rings and the executingbody; and the drilling apparatus can be automatically recovered after completing operation, so that the downhole operation automatic degree and drilling operation efficiency are improved.
本发明涉及一种用于井下辅助钻孔作业的搬运机械手,包括用于支撑整个搬运机械手的立柱本体,固定于立柱本体上的若干立柱紧固焊接体、后挡板,固定于立柱本体顶部的执行本体,以及固定于后挡板上的液压缸夹紧环;所述若干立柱紧固焊接体并排套设于立柱本体上,每个立柱紧固焊接体上横向固定有后挡板,后挡板上固定连接有液压缸夹紧环,通过液压缸夹紧环固定于井下液压支架油缸上;执行本体能伸缩运动,用于实现不同工位的吊装。本发明的搬运机械手利用立柱本体调整到合适的工作高度,通过立柱本体、液压缸夹紧环和执行本体配合,实现对井下钻孔装备起吊;当钻孔设备作业完毕时,还可实现自动回收,提高了井下作业的自动化程度和钻孔作业效率。
